Initially, the Douglas DC-4 aircraft was developed on the basis of the Douglas DC-4E model, as a multipurpose aircraft, in particular, given the fact that the design of the aircraft began in the early 40s of the last century, the aircraft was actively involved in the transportation of goods and military contingent, and after the end of the Second World War, the aircraft began to be operated by many civilian airlines as a means of passenger transportation at distances of up to 6,8 thousand kilometers.

The power plant of the aircraft Douglas DC-4 represented by four piston engines, providing a total power of 5800 hp, as well as the flight speed in 450 km \ h (the maximum speed of flight), which makes it quite competitive even with the current models of this type. Nevertheless, the production of airplanes Douglas DC-4 was limited - within five years of release, only 80 aircraft were built, of which, at the end of the year 1945 used in civil aviation in all 47 aircraft.

On board the Douglas DC-4 can accommodate up to 40 80 people (depending on the cabin configuration) that provides justifiable operation of these aircraft in the local and regional routes. However, currently operates only a few aircraft of this model - the latter two aircraft are in use belong to African airlines'South African Airways"That is supposed to write off up to 2017 years.

Despite the fact that the Douglas DC-4 aircraft was previously actively used by air carriers all over the world, it is quite difficult to fly the aircraft, while it is noted that due to the noisy Pratt & Whitney R-2000 aircraft engines, there is practically no comfort from the flights, although, Considering the time of aircraft production, the passenger compartment is made of a fairly high quality, and is quite suitable even for long routes.

In addition to the basic production version, there is also a model and modified - CanadaAir North Star, the main difference of which is less powerful, but much simpler to operate and maintain aircraft engines Rolls-Royce Merlin G, capable of developing power 1030 hp each. However, the release of this modification has been very limited.

Among other things, based on the model of Douglas DC-4 subsequently these planes were built as Douglas C-54 SkymasterActively used by the US Air Force during the conduct of hostilities during the Second World War.
